Did you know that there are only four terrestrial planets in the Solar system with a significant atmosphere, and we’ve taken photographs from the surface of all four of them?
Earth, Venus, Mars, and Titan. It shouldn’t be too hard to figure out which is which, but clicking on them will give you a bigger picture, and your answer.
Incidentally, as a terrestrial object with a significant atmosphere, the case could probably be argued for Triton too. And yes, I’m classing moons as planets here. I don’t like to discriminate against planets based on their orbital characteristics. I’m an equal opportunities astronomer.
